METALLIC RAHLWAGAR.

SPECIFICATION forming part of Letters Patent No. 752,309, dated February 16;,

. Application filed August 1,1903. Serial No. 1891358.l (No model.)

To all whom it may concern:

Be it known that I, ARNOLD STUCKI, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Metallic Railway- Cars; and I do hereby declare the following to be a full, clear, and/exact description thereof. My invention relates to railway-car underfrarnes; and its object is to provide an underro frame having a very high carrying capacity which' supports the iioor aslow as pos- In many relations it is desirable to 4have a car having a very high carrying capacity, and I 5 in order to facilitate the loading of heavy machinery, castings, &c., thereon it is desirable to have the licor supported as short a distance above the rails as possible. With cars of vely high carrying capacity it is necessary to use 2o six-wheeled trucks in order to distribute the load over a suiiicient rail-length. W'ith such trucks there is .not room enough to use a fishbelly center sill, and consequently but little of the load can be carried at the center of the car, but must he carried mostly by the Aside sills. As a consequence the latter must be made very deep in order to get the necessary strength.- Inasrnuch as the width of the car is limited by the clearance-lines of bridges and tunnels and as the six-wheeled trucks by reason of their length require considerable lateral space in passing around curves, so'me special construction ofside sills must be provided to permit the trucks to pass. properly around curves.

The object of my invention is 'to provide a 'car `under-frame adapted for the purposes above specified and wherein the proper clearance for the trucks and also the necessary 40 strength is secured. l

To this end it consists in a car-underi'rame having peculiar and especially constructed side sills of very great depth, so to get the necessary carrying capacity, said sills being cut away opposite the journal-boxes oi' thc truck, so as to permit lateral movement of,r

said journal -hoxvs when the truck swings around curves.

The invention also comprises other details of construction hereinafter specified and claimed.

In the accompanying drawings, Figure' l is a plan vieur of one-half of my .improved underi'ram'e. Fig. 2 is a side view of the same. Fig. 3 is a-central longitudinal section through the same. Fig. 4;. is an end view thereof. Fig.5 is a cross-section on the line 5 5, Fig. l. Fig. .6 on its right-hand portion is a crosssection on the line 6 6, Fig. l, and on its lefthand portion on the line 6a 6, Fig-1; and

Fig. 7 is a side view Vof a modification,

In order to better illustrate the principle of my invention, I have shown in several of the views the outline of a truck for supporting the underframe. rIhis truck comprises the wheels l, axles 2, journal-boxes 3,Y side frames 4:, holsters 5, bridge 6, cross-bearer 7, and center hearing-plate 8. The constructions of these several parts of the truck are fully illustrated, described, and claimed in an application of even date herewith, Serial No. 169,357, and specific description thereof will not be made in the present case. Any form ot' six-wheeled truck of suilicient strength to carry the necessary load may be used in connectionl with my underframe, although the truck shown is peculiarly adapted for carrying the under-frame very close tothe rails..

On account of the great length of sixwlieeled trucks and the vconstruction .thereofv there is not room enough to use fish-belly center sills. 1 0, preferally rolled channel-beams oi' moderate depth, arc employed. These sills will takecare of all ofthe end shocks, but will carry only a small portion of the load. The latter is carried almost exclusively by the side sills .11, which are made very' strong vand which project down considerably'below the journalboxes 3. The clearance in tunnels and bridges limits the width of the cars, and consequently these side sills cannot he placed too far apart, and inasmuch as the six-wheeled trucks in passingarou nd curves swinglaterally to a considerable extent there is dangerof the journalboxes-coming in contact with these low-hang- Consequently straight center sills facilitate inspection' of the ing side sills. Asa consequence the side sills are so constructed that they are open opposite the journal-boxes. i In Fig. 7 this principal is' clearly shown, wherein the side sills are of plate-girder construction and provided with holes 12 opposite the journal-boxes. Preferably, however', the side sills are of an opentrussed or lattice girder construction, having the lattice-work so arranged that open spaces will be left opposite the journal-boxes. This latter form of side sills is shown in other .figures of the drawings. These side sills each comprise a plate '13, having its upper edge substantially at the floor-level and projecting downwardly approximately one-third of the depth of the sill. Riveted to this plate is an angle-bar 14, which, together with the plate, forms the upper or compression member of the girder. The lower or tension member ofthe girder is formed by a langed member, such as the anglel bar15, and this may be further strenghened by a section of plate 16, if desired. The top and "bottom members of the sill are connected by suitable vertical members 417 and diagonal members 18, which are riveted either directly to said members or connected thereto by means of'conne'ctin'g-plates 19. These vertical and diagonal members are arranged, as shown in Fig. 2, to leave open spaces or openings opposite the journal-,boxes 3, so as to permit the free lateral movement of the trucks in passing around curves and also to journal boxes and. bearings. n

The longitudinal vmembers of the underframe are connected at intervals by means of the shallow cross-ties 20, which may be of any preferred form and are shown as pressed panshaped plates placed between the side and center sills and also between the center sills.. At two points near the middle of the underframe are deeper cross-ties or diaphragms composed of lling-pieces 22, placed between the side and center sills and also between the center sills, said iilling-pieces being substantially the same depth as the center sills, and a cross-connecting member 23, placed underneath these filling-pieces and preferably secured thereto, vas shown yin Fig. 5, and extending from side sill to side sill and secured thereto. All of the ,I members of these cross-ties-that is, the 611- ing-pieces 22 and the cross-1 pieces 23--are formed of pressed pan-shaped members, thus providing flanges for securing the s ame to the car-sills and to each other. These cross-connecting members, however, maybe other than pan-shaped members, if desired. At the ends of the underframe the downwardly-projecting portions of the side sills are connected and held in place by meansof diagonal rods 25, having one end secured to the lower' chords of the side sills and the opposite ends secured to the lower edge of the end sill. The end sillmay be of any preferred construction, but preferably is a pessed channel-shaped member of the cross-section sh own in Fig. 3, having an opening 27 therethrough for the passage of the shank of the draw-bar and preferably .having a bulged-up portion 28 at its middle to give it-suliicient strength above the draw-bar opening, this being necessary because said opening must be placed relatively high by reason of the low position of the underframe. The draft-lugs 30 are riveted directly to the center sills, and to give sulicient space for the draft-,rigging the floor-plates are bulged upwardly near the end at the center of` the car, as shown at 31.

The body -bolster 32 is placed above the sills, this being necessary because of the low position ofthe underframe, which leaves inlsuiiicient space between the truck-bolster and the center and side sills. The body-bolster `maybe of any suitable beam construction,- that lshown being an inverted trou gh'member having outwardly-turned flanges 33 at its lower v edge for riveting to the longitudinal sills. This trough is strengthened at the ends by braces 34 and at the middle by braces 35.

Fig. 6 and preferably formed Io f pressed metal are placed in the angle between saidv bolster and the outer faces of the center sills and riveted to both. Brace-pieces 39 are riveted to the center and sidey sills and lower edges of the cross-tie pieces20. The floor-plates 39 are riveted directly to the upper anges of the longitudinal sills and also to the cross-tie members and to the loutwardly-projecting =flanges of the body-holsters. Although this arrangement of floor-plates is shown in this case, it willibe understood that a wooden oor,.n1 ay be use i The underframe described is very strong and lcarried very low, thus facilitating the loading and 'unloading of heavy objects. Furthermore, itis as narrow as is possible with such deep side sills and affords ample clearance `for` bridges and tunnels. A
